Each RWS200 system is Vaisala Road Weather Station RWS200 of the road. Remote sensors are easier to install and maintain, as no traffic control or cutting of the road surface is required. This also provides additional safety by taking the workers out of the roadway. In addition, the remote surface state sensor provides a value of grip that gives decision makers a quantitative reading of the current road slipperiness. This grip value can be used for a variety of decision-making tools, such as performance indexes or a trigger for variable message signs. Atmospheric sensors Atmospheric sensors enhance the performance of the algorithms when determining the road and runway surface conditions. They also provide additional information that can be critical to the Over the years, several studies and overall traveling environment. This kind Challenges of road research have been done to prove that of information can be, for example, alert maintenance road weather technology provides a of heavy rain. To keep the roads and runways safe and significant return on your investment. passable at all times, the pavement and This largely comes through operational atmospheric weather must be savings of road maintenance and continuously monitored. Weather Intelligent Transportation Systems (ITS) conditions such as snow and ice, heavy activities, which improve mobility and rains, fog, high winds, and sand storms increase safety of travelers. can impact road and runway safety in many different ways. Surface sensors Unfortunately, you cannot usually Road weather stations consist of a observe the weather impact from your variety of sensors that collect office window, so it is important to have atmospheric and road or runway a reliable tool for information gathering. condition data. The sensor selection depends on your needs. Importance of road weather Surface sensors come in two types, stations embedded and remote. Embedded Road weather stations, also known as sensors are placed into the road or Road Weather Information Systems runway surface. They provide data on the (RWIS), have been developed for several conditions on their surface. decades to collect information about Remote (or non-invasive) sensors are a road and runway conditions. The stations newer innovation using infrared and laser not only collect data in remote locations technology to measure surface but also provide a quantitative conditions. They are installed on the side measurement to weather, which in the past was typically done with the human eye. Why RWS200? solution to improve road, rail, or runway winter maintenance activities in your organization. RWS200 features a configurable graphical user interface for a variety of data viewing and maintenance needs. The use of Ethernet communications and 3G/4G cellular network enable remote access to RWS200 and continuous data flow to data collection systems. However, one of the reasons for having an onsite processor is the ability to store historical data locally for at least two weeks. Observation data is not lost even if remote communication is lost. In winter road and runway maintenance, accurate and reliable data must be trustworthy and available when you need Intelligent Scalable to make decisions. The Vaisala Road Weather Station What if you do not want or need a full- RWS200 is the key component to Vaisala feature, complete weather station?

RWS200 is scalable, allowing you to add RWS200 is intelligent: it contains several the features that you need to match the sophisticated algorithms that bring in requirements at each location. You can raw data from the surface state sensors. choose from different enclosures, various By using other atmospheric sensor options, or use a selected set of observations, RWS200 can produce existing retrofit sensors, if you want. more accurate surface state analysis. If you need to upgrade the station later RWS200 is equipped with smart power on, you can add new sensors or update management. The full featured RWS200 the station software to add new features. comes with a backup battery. When main This allows you to fully benefit from the power is lost, RWS200 detects the future improvements in sensor and change and begins shutting down communication technology, and ensure operations that drain the most power. your return of investment. This ensures that in an environment where power is not always stable, Reliable RWS200 continues to provide RWS200 is not just a roadside processor observations and access to the system as designed to collect, store, and transmit long as battery power is available. data from surface sensors. RWS200 Vaisala sensors are sold around the world provides a complete road weather for many different applications, both separately and with Vaisala weather stations. RWS200 supports a large range of Vaisala sensors and a selected set of third-party sensors.
